“…The converter in this paper requires 80 V on the average because the switches from Q1-Q3 requires a minimum voltage rating of 80 V. The critical factors in selecting the proper switch are based on on-state resistance, and rise time and fall time when ON and OFF period of the switch. Few switches require body diode or an additional diode across the switch [1] , [2] , [3] . The switch Q2 has to change between PV panel voltage and Earth, so it exhibits power pulsation during switch ON/OFF condition.…”

“…With one-stage output at the light-load condition, the buck converter should operate at the discontinuous current mode (DCM). After the careful analysis, the converter delivers a higher efficiency during DCM with one diode for the ground route, compared with the synchronous converter using MOSFET at the ground path [2] , [3] . The efficiency at high load is less due to the diode in the ground path of the asynchronous buck converter.…”

This set of data is being used to calculate the design parameters of the solar photovoltaic (PV) charge controller. The data presented in this paper are used to design an advanced charge control with higher capacity and more possible real-time applications. This design parameters of the controller will be useful for the off-grid systems, automatic street light, and signs control, etc., which requires the medium-level power, and more reliable operation. The design set of parameters such as inductance, switching frequency, duty cycle, power loss, and the efficiency are given in this paper for the rating of the 500 W charge controller. The data captured are compared with the various power level selection along with the different power semiconductor switches.

“…In photovoltaic (PV) generation systems, the energy produced is limited by the efficiency of solar panels, which is generally between 18 and 23% [1]. The low conversion efficiency of a PV panel is due to the physical characteristic of PV conversion, and the dependence of its maximum power point (MPP) with atmospheric conditions [2]. Thus, the use of a maximum power point tracking (MPPT) technique to optimize the energy produced becomes essential [3,4].…”

This paper presents the design and implementation of a digital control strategy for a Buck converter, used as a solar charger of valve-regulated lead acid (VRLA) batteries. The control system consists of two fuzzy logic controllers (FLCs), which adjust the appropriate increment of the converter duty cycle based on battery state of charge according to a three-stage charging scheme. One FLC works as a maximum power point tracker (FLC-MPPT), while the other regulates the battery voltage (FLC-VR). This approach of using two different set of membership functions overcomes the limitations of the battery chargers with a single control function, where the voltage supplied to the battery is either not constant due to the operation of the MPPT algorithm (possibly damaging the battery) or is constant due to the operation of the voltage control (hence, MPP cannot be achieved). In this way, the proposed control approach has the advantage of extracting the maximum energy of the PV panel, preventing battery damage caused by variable MPPT voltage, thereby extending the battery’s lifetime. Moreover, it allows overcoming of the drawbacks of the conventional solar chargers, which become slow or inaccurate during abrupt changes in weather conditions. The strategy is developed to be implemented in a low-cost AT91SAM3X8E Arduino Due microcontroller. Simulations by MATLAB/Simulink and experimental results from hardware implementation are provided and discussed, which validate the reliability and robustness of the control strategy.

“…Since the power saved in the battery is in the form of DC Voltage, and the power required by lighting and sound system is in the form of AC Voltage, an inverter is required to convert DC voltage from battery to supply the lighting and sound system. The transfer of power supply from electricity grid to the emergency power supply is carried out using Automatic Transfer Switch (ATS) that enables fast power replacement [2]- [4]. This will make the situation of prayer calm and people performing prayer can still concentrate on their prayer.…”

Emergency power supply is necessary for a mosque particularly when prayer is happening while power cuts. The important devices required to remain alive at this event are lighting and sound system. For this purpose, a battery is needed to supply the devices and the lighting and movement sensors that used to control the emergency power supply. The battery is powered by a solar photovoltaic (PV) panel. The power supply switching between main power and battery is regulated by Automatic Transfer Switch. A 20 Ah, 12 Volt battery supplied by 50 WP solar PV panel is used to back up the power for 6 W LED light and sound system. The system is implemented on the Mosque of Al-Bakri, Mojosongo, City of Surakarta. Research purpose of implementing this system is to solve the problem of power cuts during worship. This research used survey and measurement methods. In conclusion of implementing this system the prayer may continue even the electricity went out.
